Designed to re-create recording-studio sound for your PC environment, the Micro Innovations MM300S subwoofer speaker system boasts a powerful central bass speaker that enhances lower frequencies and improves reproduction quality of music and theatrical sounds found in high-end games. Classic midrange and high-end sound from the two satellite speakers, combined with the deep bass from the 12-watt powered subwoofer plus dual-channel stereo amplification, creates depth in your audio environment. An adjustable bass control delivers broad-based sound from all types of music, and a master volume control allows you to adjust the sound right from the speakers. <p>The system includes a headphone jack for private listening and comes with a one-year limited parts-and-labor warranty.
